How salt chlorinator works
Operation of the salt chlorinator
Operating steps of the salt chlorinator
Add salt
To begin with, For the salt chlorinator to work, we must have added 5kg per m3 of sodium chloride water to the pool. (commonly known as salt (NaCl)).
Electrolysis process
When the pool water passes through the salt chlorinator, an electrolysis process is generated through the electrical energy caused by the salt electrolysis equipment.
Water conversion
At this time, Pool water is converted into sodium hypochlorite (NaClO).
Free chlorine production
Next, the transfer of electrons and ions occurs automatically on the electrodes of the salt electrolysis equipment. All this in order to achieve the production of free chlorine (Cl2) automatically (without stabilizers or ammonia).
Destruction of organic matter and pathogens
Through the free chlorine generated the destruction of organic matter and pathogens is achieved, therefore we obtain a correct disinfection of the pool water.
Extra in the salt chlorinator: pool orp probe
Currently, there are many salt electrolysis equipment which have an integrated ear probep pool, which is installed in the water return tube to provide us with the measurement of the amount of chlorine or disinfectant present in the pool water.
Finally, we provide you with the direct link to the very important control factor if you have a salt chlorinator: orp pool or in other words redox pool.
Video how a Saline Electrolysis system for swimming pools works
After watching the video, the questions about the salt pool.
- How a salt electrolysis system for swimming pools works
- What are salt pools?
- How they generate their own chlorine.
- Salt "chlorinator" is better than chlorine tablets
- Advantages of the salt chlorinator
How to know if the salt chlorinator works
Water bucket test to verify the operation of the salt chlorinator
- A very simple and effective way to check if the salt chlorinator works is to fill a bucket with water or a bottle and insert the chlorinator electrode inside until the water completely covers it. Note that the connectors should not get wet, so be very careful with the water level, if necessary empty the bottle or bucket.
- We launch the team saline chlorination after a few seconds the water should become cloudy forming a kind of foam generated by the gas particles that are released from the process. In this case it tells us that the equipment is performing the electrolysis correctly and consequently that it is working correctly.
- If you still have doubts about its operation, you can check the chlorine level in the same bucket or bottle of water where you have carried out the checks, this must be very high since the number of cubic centimeters is very small. Another sign of correct operation is a smell similar to that of bleach given off by the bucket or bottle of water where the salt chlorinator is acting.
Other verifications to test the operation of the pool chlorinator
- Confirm the return water flow to make the comparison with the measurement extracted from the water in the pool glass.
- Perform the test outside the pool, thus isolating any other factor that may influence the measurements.
Start-up of saline electrolysis
Steps to start up salt electrolysis
- First of all, to start up the salt chlorinator, we must make sure that both the salt chlorination system and the peristaltic dosing pump are connected.
- On the other hand, Depending on the m3 of pool water, we will add the necessary amount of pool salt inside the glass and VERY IMPORTANT with the pool pump running..
- To clarify, the salt must be distributed throughout the periphery of the pool glass evenly so that it can accommodate the entire volume of water; This way we will ensure that it dissolves quickly.
- So, we will add about 4kg of specific salt for saline chlorination of the pool for each m3 of water in our pool.
- Moreover, we must recirculate the pool water based on manual filtration during what would be a filtration cycle (basically until the salt has dissolved in the water and with the salt electrolysis stopped).
- The next step is check pool values and we balance them if required: pH between 7-2 and 7,6 and Pool alkalinity 80-120p.pm
- To conclude, We check how the pool filter is and if required we carry out a filter cleaning.
- Finally, we connect the saline electrolysis system with 100% of the production and we adjust it as needed to its proper power.
How to measure pool salt
Ideal measurements of pool salt
Ideal measurements of pool salt: between 4 – 5 grams of salt/liter.
Measure pool salt
Salt levels in the pool can be altered by factors that alter its correct concentration, as well as the proper disinfection of the water.
Some of them being the high temperature and the lack of cleaning of the filters.
Therefore, measuring the concentration of salt in the pool is necessary to take advantage of all the advantages of salt chlorinators.

What maintenance does a saltwater pool need?
Checks for maintenance of saline electrolysis:
1. PH control: The ideal pH should have a value of 7,2.
2. Chlorine control: Check that the chlorine is between 0,5 – 1ppm. If you find low chlorine levels, the device's operating hours should be increased.
3. Salt control: Check that it is between 4 – 5 grams of salt/liter. If salt is missing, it must be added. Otherwise, empty the pool a little and renew the water.
4. Cleaning leaves and insects from the skimmer basket.
5. Cleaning the filters.
6. Monthly review of the cleaning the electrodes and terminals of the cell.
7. Check that there are no water leaks.
8. Check that there are no air inlets.
maintenance of a salt pool: How to clean cells from salt chlorinators
Saltwater pool care: cell cleaning
Although the cells of salt chlorinators have automatic cleaning, there are times when it is not enough and manual cleaning must be done.
Therefore, we must have a periodic routine to Inspect if there is presence of lime in our pool chlorinator cell.
Salt water pool maintenance procedure: clean the salt chlorinator cells
Guidelines for cleaning cells in saltwater pool maintenance
- The first step of the manual cell cleaning procedure will be Turn off both the pool pump and the salt chlorinator.
- Then We will disconnect the cell, unscrew it and remove it.
- Then We will wait several days for the cell to dry so that the lime plaques come off by themselves or are simply removed by giving it a few small taps. (Attention: we cannot introduce any incisive element into the cell).
- If the previous step does not work, we will have to immerse the electrodes in a solution of hydrochloric acid and water.
- As soon as the lime comes off, rinse the cell with water, dry the terminals and install the salt chlorinator again.
Saltwater pool maintenance video: cleaning the cell of the saline electrolysis equipment
Tips for cleaning a saltwater pool
- To clean the pools of bacteria and enjoy properly preserved water, a salt chlorinator is installed that maintains it very easily.
- But, bacteria, algae, lime and other dirt accumulate in the electrolysis cell.
- And when the equipment does not have a self-cleaning system due to electrical polarity, it is necessary to clean the saline pool purifier with certain frequency so that it produces natural chlorine.
- But plates should never be cleaned with metal objects (Plastic utensils must be used carefully so that they do not scratch).
Considerations for saltwater pool maintenance
- Plates should never be cleaned with metal objects. (Plastic utensils must be used carefully so that they do not scratch).
- When there is a high lime content, extra care must be taken. Because the high lime contents form sediments that cover the metal plates on the electrodes, decreasing chlorine production.
Steps to clean a saltwater pool
- Periodically analyze all the values of the pool water (pH, free chlorine, pool ORP, saturation level of isocyanuric acid in the pool, alkalinity, metal level, etc.) and if required add chemical product.
- Clean the pool glass.
- Ensure the appropriate filtration hours indicated according to the pool available. Click pool filtration to learn more about this aspect.
- Carry out routine procedures according to the bathing season and use of the pool for the different elements of the pool: the pool pump, the filter, etc.
- Also maintain good cleanliness of the generator cell.
